ETS-Lindgren 2090 Controller - Manual (Page 106)

Appendix A: Model 2090 GPIB Command Reference Model 2090 Multi-Device Controller
CC
Compatibility: All
Description: Instructs the turntable to move in the counterclockwise direction. This
movement is limited by the counterclockwise limit.
Devices: Turntables
Syntax: CC
Example: CALL ibwrt (TableUD%, "CC") ' Direct turntable to rotate
' counterclockwise.
See Also: CW
CL
Compatibility: 1050, 1060
Description: Queries the turntable's counterclockwise limit. The value returned is either in
N1 (XXX) or N2 (XXX.X) format depending upon the current numeric mode.
Negative values are preceded by a "-" minus sign. This command is obsolete.
On the models 1050 and 1060, this command changed the front panel to
display the counterclockwise limit and prepared the controller to respond to
all future reads with that limit. This is not compatible with the IEEE 488.2
standard; the program must send the CL command before each read. For
programs which will not be used with a model 1050 or 1060, use the CL?
Command.
Devices: Turntables
Syntax: CL
Response: [-]XXX[.X] Value of the counterclockwise limit setting in
degrees.
Example: CALL ibwrt (TableUD%, "CL") ' Query turntable counter-
' clockwise limit
CALL ibrd (TableUD%, rdbuf$) ' Read response
See Also: CL 1090/2090, CL?
CL
Compatibility: 1090, 2090
Description: Changes the counterclockwise limit of the device. The specified value must
be less than the clockwise limit and between -999.9 and 999.9. Note that,
unlike editing from the front panel, the 2090 allows setting the limit above the
current position from the GPIB.
Devices: Turntables
Syntax: CL [+/-] XXX[.X]
+ Optional for positive values
- Necessary for negative values
XXX[.X] Decimal value for the counterclockwise limit to be
set in degrees.
In N1 mode .X is ignored
In N2 mode .X is optional.
Leading zeros are optional.
Example: CALL ibwrt (TableUD%, "CL -100") ' Change CCW limit of the
' turntable to -100 degrees.
CALL ibwrt (TableUD%, "CL 235.7") ' Change CCW limit of the
' turntable to 235.7 degrees.
